DIY Weekly dry-erase board using a collage frame found at Walmart! Print days of week onto pretty paper, and put a different day into each section (behind glass). Write on glass with dry-erase markers.
Simple picture puzzle for younger toddlers. (calendar pictures too) Could add magnets to put together on fridge. (magnets like from phone book ads.) FYI: Grandparents& pictures would keep their faces fresh in child& memory.
